研究了核壳微凝胶吸附在硅片上的溶胀和收缩行为。在这些体系中，核由交联聚（N-异丙基甲基丙烯酰胺）制成，壳由交联聚（N-正丙基丙烯酰胺）组成。在悬浮液中，这些颗粒在两种聚合物的较低临界溶解温度之间的温度区间内表现出延长的线性溶胀行为。使用椭圆偏振和原子力显微镜，我们表明，这种线性响应也观察到吸附状态。
We study the swelling and shrinking behavior of core shell microgels adsorbed on silicon wafers. In these systems, the core is made of cross-linked poly(Nisopropylmethacrylamide) and the shell consists of cross-linked poly(N-n-propylacrylamide). In suspension, these particles exhibit an extended linear swelling behavior in the temperature interval between the lower critical solution temperatures of the two polymers. Using ellipsometry and atomic force microscopy, we show that this linear response is also observed in the adsorbed state.
